But there it is Niblet. In the assembly manual, I find 2 part #s for the shifter asm., 9789337 for the Heavy Duty 3-Speed and 9789336 for a 4-speed. I know the 1967 SS 350 ordered with a heavy-duty Borg-Warner 3-speed could only be had with a floor shift while the standard Saginaw 3 speed came with a column shift unless a console was ordered. I strongly suspect the shifter mechanism for both the standard and heavy-duty 3-speed transmissions are identical only having different shift rods & the mounting bracket stabilizer. I would think even the majority of shifter mechanism parts between the Inland 3-speed & 4-speed shifter are the same, maybe even using the same shifter lever. Do all known SS 350 's with a heavy-duty transmission have a "Muncie" shifter handle and then also the SS 396's? Did the Saginaw 4-speeds also get a shifter mechanism with "Muncie" on the handle? If so, the "Muncie" handle, while a decorative upgrade, really had nothing to do with having an aluminum transmission. If your SS 350 has a 3-speed lever with "Muncie" on it, I can't see a reason mine couldn't also have been built that way even if yours was supposed to be and mine was an error. I suspect those shifter body mechanisms came from the same parts bin on the line unless they were delivered from Inland preassembled with all their shift rods in place. If this was an error, it was created at the Inland shifter assembly plant. Can anyone who has disassembled both Inland 3-speed & 4-speed shifters confirm that the shifter handle is either identical or different between the 2 kinds?
I have no intention of making a big deal out of this but what I do know is that when I purchased my car in September of 1976, long before almost any of us ever spent 1 second considering any of this important, my car, which even today is still largely equipped with almost all of its original assembly line parts, came with a 3-speed shifter that had a "Muncie" handle on it. I have no idea if someone in the preceding 10 years may have caused this change to happen or did my car come through assembly with an error from what it should have had.
